So, HN, are HDR monitors worth it? I remember ~10 years ago delaying my monitor purchase for the HDR one that was right around the corner, but never (in my purchasing scope) became available. Time for another look? The utility of HDR (as described in the article) is without question. It's amazing looking at an outdoors (or indoors with windows) scene with your Mk-1 eyeballs, then taking a photo and looking at it on a phone or PC screen. The pic fails to capture what your eyes see for lighting range.

For gaming, definitely. An HDR Oled monitor is so immersive.

I think it depends on the screen and also what you use it for. My OLED is unusable for normal work in HDR because it's designed around only a small portion of the screen being at max brightness - reasonable for a game or movie, but the result is that a small window with white background will look really bright, but if I maximize it, it'll look washed out, grey not white. Also the maximum brightness isn't even that bright at 800 nits, so no HDR content really looks that different. I think newer OLEDs are brighter though. I'm still happy with the screen in general, even in SDR the OLED really shines. But it made me aware not all HDR screens are equal. Also, in my very short experiment using HDR for daily work I ran into several problems, the most serious of which was the discovery that you can no longer just screenshot something and expect it to look the same on someone else's computer.

To be pedantic, this has always been the case... Who the hell knows what bonkers "color enhancement" your recipient has going on on their end? But (more seriously) it's very, very stupid that most systems out there will ignore color profile data embedded in pictures (and many video players ignore the same in videos [0]). It's quite possible to tone-map HDR stuff so it looks reasonable on SDR displays, but color management is like accessibility in that nearly noone who's in charge of paying for software development appears to give any shits about it.

IF you have a display that can it roughly a 1000 nits, then for movies and games yes definitely the difference with SDR is pretty huge. If you have say a 400 nits display the HDR may actually look worse than SDR. So it really depends on your screen.

  Honestly, I find the extended brightness FAR less important than the extended color gamut. I have a ~300 nit VA monitor that I'm generally quite happy with and that looks fantastic with well-built HDR renderers. Given that monitors report information about their HDR minimum and maximum panel brightness capabilities to the machine they are connected to, any competently-built HDR renderer (whether that be for games or movies or whatever) will be able to take that information and adjust the picture appropriately.

HDR gaming: Yes. HDR full screen content: Yes. HDR general desktop usage: No. In fact you'll probably actively dislike it to the point of just turning it off entirely. The ecosystem just isn't ready for this yet, although with things like the "constrained-high" concepts ( https://www.w3.org/TR/css-color-hdr-1/#the-dynamic-range-limit-property https://www.w3.org/TR/css-color-hdr-1/#the-dynamic-range-lim... ) this might, and hopefully does, change & improve to a more pleasing result Also this is assuming an HDR monitor that's also a good match for your ambient environment. The big thing nobody really talks about wiith HDR is that it's really dominated by how dark you're able to get your surrounding environment such that you can push your display "brightness" (read: SDR whitepoint) lower and lower. OLED HDR monitors, for example, look fantastic in SDR and fantastic in HDR in a dark room, but if you have typical office lighting and so you want an SDR whitepoint of around 200-300 nits? Yeah, they basically don't do HDR at all anymore at that point.

  I use HDR for general usage, Windows ruins non-HDR content when HDR is enabled due to their choice of sRGB tf. Luckily every Linux DE has chosen to use the gamma 2.2 tf, and looks fine for general usage. I use a mini-led monitor, and its quite decent, except for starfields, & makes it very usable even in bright conditions, and HDR video still is better in bright conditions than the equivalent SDR video. https://github.com/dylanraga/win11hdr-srgb-to-gamma2.2-icm https://github.com/dylanraga/win11hdr-srgb-to-gamma2.2-icm

Yes but with asterisks; Best way I can describe it: You know the 0-10 brightness slider you have to pick at the start of a game? Imagine setting it to 0 and still being able to spot the faint dark spot. The dynamic range of things you can see is so much expanded. Early HDR screens were very limited (limited dimming zones, buggy implementation) but if you get one post 2024 (esp the oled ones) they are quite decent. However it needs to be supported at many layers: not just the monitor, but also the operating system, and the content. There are not many games with proper HDR implementation; and even if there is, it may be bad and look worse — the OS can hijack the rendering pipeline and provide HDR map for you (Nvidia RTX HDR) which is a gamble: it may look bleh, but sometimes also better than the native HDR implementation the game has). But when everything works properly, wow it looks amazing.

  > You know the 0-10 brightness slider you have to pick at the start of a game? Imagine setting it to 0 and still being able to spot the faint dark spot. The dynamic range of things you can see is so much expanded. Note that HDR only actually changes how bright things can get. There's zero difference in the dark regions. This is made confusing because HDR video marketing often claims it does, but it doesn't actually. HDR monitors do not, in general, have any advantage over SDR monitors in terms of the darks. Local dimming zones improve dark contrast. OLED improves dark contrast. Dynamic contrast improves dark contrast. But HDR doesn't.
  - eschatology 1y ago
    My understanding is that on the darker scenes (say, 0 to 5 in the brightness slider example), there is difference in luminance value with HDR but not SDR, so there is increased contrast and detail. This matches my experience; 0 to 5 look identically black if I turn off HDR
    - kllrnohj 1y ago
      You may have a monitor that only enables local dimming zones when fed an HDR signal but not when fed an SDR one, but that would be unusual and certainly not required. And likely something you could change in your monitors controls. On things like an OLED, though, there's no difference in the darks. You'd see a difference between 8bit and 10bit potentially depending on what "0 to 5" means, but 10-bit SDR is absolutely a thing (it predates HDR even) But like if you can't see a difference between 0 to 5 in a test pattern like this https://images.app.goo.gl/WY3FhCB1okaRANc28 https://images.app.goo.gl/WY3FhCB1okaRANc28 in SDR but you can in HDR then that just means your SDR factory calibration is bad, or you've fiddled with settings that broke it.

I've been thinking of moving out of the Apple ecosystem but after seeing Severance on my iPhone Pro screen I feel like I want the keep the option to have the same HDR experience for movies specifically. With HDR support landing in Linux just a month ago I'm inclined to spend on a good monitor. However, I have IPS HDR 600 monitor but I never felt that the screen was as glorious as the iPhone screen. I'd also be interested in hearing whether it makes sense to look into OLED HDR 400 screens (Samsung, LG) or is it really necessary to get an Asus ProArt which can push the same 1000 nits average as the Apple XDR display (which, mind you, is IPS).

Dunno if it's just my screen or setup but on windows I have a Dell U4025QW and HDR on the desktop just looks strange, overly dull. Looks good in games but I have to manually turn it on and off each time on the screen. On my Macbook Pro only activates when it needs to but honestly I've only seen one video [1] that impressed me with it, the rest was completely meh. Not sure if its because it's mostly iPhone photography you see in HDR which is overall pretty meh looking anyway. [1] https://www.youtube.com/watch?v=UwCFY6pmaYY https://www.youtube.com/watch?v=UwCFY6pmaYY I understand this isn't a true HDR process but someone messing with it in post, but it's the only video I've seen that noticeably shows you colors you can't see on a screen otherwise.

A lot of monitors that advertise HDR support really shouldn't. Many of them can decode the signal but don't have the hardware to accurately reproduce it, so you just end up with a washed out muddy looking mess where you're better off disabling HDR entirely. As others here have said, OLED monitors are generally excellent at reproducing a HDR signal, especially in a darker space. But they're terrible for productivity work because they'll get burned in for images that don't change a lot. They're fantastic for movies and gaming, though. There are a few good non-OLED HDR monitors, but not many. I have an AOC Q27G3XMN; its a 27" 1440p 180hz monitor that is good for entry-level HDR, especially in brighter rooms. It has over 1000 nits of brightness, and no major flaws. It only has 336 backlight zones, though, so you might notice some blooming around subtitles or other fine details where there's dark and light content close together. (VA panels are better than IPS at suppressing that, though.) It's also around half the price of a comparable OLED. Most of the other non-OLED monitors with good HDR support have some other deal-breaking flaws or at least major annoyances, like latency, screwing up SDR content, buggy controls, etc. The Monitors Unboxed channel on YouTube and rtngs.com are both good places to check.
- Sohcahtoa82 1y ago
  I think an OLED is basically an absolute necessity for HDR content. My current monitor is an OLED and HDR in games looks absolutely amazing. My previous was an IPS that supported HDR, but turning it on caused the backlight to crank to the max, destroying black levels and basically defeating the entire purpose of HDR. Local dimming only goes so far.
  - nfriedly 1y ago
    > My previous was an IPS that supported HDR, but turning it on caused the backlight to crank to the max, destroying black levels and basically defeating the entire purpose of HDR Yeah, that's kind of what I meant when I said that most monitors that advertise HDR shouldn't. The AOC monitor is the third or fourth one I've owned that advertised HDR, but the first one that doesn't look like garbage when it's enabled. I haven't gone oled yet because of both the cost and the risk of burn-in in my use case (lots of coding and other productivity work, occasional gaming).
SebastianKra 1y ago
Apple's Displays yes. But I got a Phillips 4k OLED recently, and I'm already regretting that decision. I need to turn it off every 4 hours to refresh the pixels. Sometimes an entire line of pixels is brighter than the rest. I wiped it with a cloth while pixel refresh was running, and then saw burned in streaks in the direction of the wipe. And thats now that all the LEDs are still fresh. I can't imagine how bad it will be in a few years. Also, a lot of Software doesn't expect the subpixel arrangement, so text will often look terrible.

HDR when it works properly is nice, but nearly all HDR LCD monitors are so bad, they're basically a scam. The high-end LCD monitors (with full-array local dimming) barely make any difference, while you'll get a lot of downsides from bad HDR software implementations that struggle to get the correct brightness/gamma and saturation. IMHO HDR is only worth viewing on OLED screens, and requires a dimly lit environment. Otherwise either the hardware is not capable enough, or the content is mastered for wrong brightness levels, and the software trying to fix that makes it look even worse.
